Introductions... Engineer, long time motorcyclist, tinkerer, and builder. Started getting into bicycle and scooter builds the last couple years.I've only done electric-powered bicycles until now: in the middle of a 2 stroke gasbike build. I work a lot with the Nuvinci hubs; I know the tech and design fairly well and have tested their performance extensively. I can't get into details for proprietary reasons, but I can be of some help.
